Tensile Adhesion Tester NOVOTEST AC-1
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another. In the field of quality testing, adhesion of coatings to the base material, such as: paints, plastic, epoxy mixtures, sprayed metal, laminate to wood and other metal and polymer coatings, is most often measured.
Tensile Adhesion Tester NOVOTEST AC-4624 is a pull-off type adhesion tester for determining the adhesion strength in MPa and can be used in accordance with EN13144, ISO4624 and ISO16276-1.

Cross Cut Adhesion Tester NOVOTEST AN-1
Cross Cut Adhesion Tester is designed to comply with: ISO 16276-2, ISO 2409, DIN 53151, ASTM B 335, ASTM D 3002, BS 3900-E6, BS EN ISO 2409, NF T 30-038.
Cross Cut Adhesion Tester NOVOTEST AN-2409 is designed for cuts (parallel or lattice) adhesion testing method , and for thickness range of paint coatings up to 200 µs, according to ISO 2409, ISO 16276-2, ASTM B 3359. Device can be used on both flat and curved surfaces.
The method of parallel or lattice cuts is consist of assessing the adhesion value while cutting through the coating down to the substrate by a multi-blade knife with the distance between the blades 1 mm, 2 mm or 3 mm which produces a strip or grating with the same pitch. Than the place of cutting is to be cleaned and visually analysed the value of adhesion by the nature and the area of destruction of the coating.
Structurally Cross Cut Adhesion Tester NOVOTEST AN-2409 is consist of plastic handle and metal head for fastening multiblade knife, which is made of tool steel. Each knife has six main and two restrictive blades. User can sharpen blunted blades. -
Cross Hatch Adhesion Plate NOVOTEST AH-AR
The instrument is designed to measure the adhesion value of coatings in compliance with ISO 16276-2 and ASTM D 3359.
Adhesion tester consist of a flat steel plate with normalized slits, which is used as a template to perform incisions with the knife.
Application
The adhesion plate is placed on the test surface, the coating is cut with the knife up to the substrate, after which the plate is rotated and performed the second cut 30 degrees to the first in the form of an X (X-cut). Incisions are cleaned with a brush or with adhesive tape, after that, the adhesion value is visually evaluated according to the point system.

Peel Adhesion Tester NOVOTEST AP-1M
Adhesion tester AP-1M is designed to measure the adhesive strength value of the coatings on different structures, as well as to determine the adhesion value of polymeric insulating tapes which are generally used for pipes insulation. Adhesion tester AP-1M is reliable and easy in operation.
Design of the instrument
Adhesion tester AP-1M consists of a body with removable clamp for holding the peelable strip of tested material with built-in dynamo-meter were breakout force is displayed. The design of the instrument allows user to set (control) the angle of peeling.
The dynamo-meter’s scale is applied to pull the rod, that significantly improves it’s usability, compared to existing analogues: user’s hand never overrides the scale of the instrument. Adhesion tester has reliable construction of stainless steel, that guarantees it’s long life. The design of instrument allows user to operate at low temperatures or conditions of high humidity and dust.

Bitumen and Mastic Insulation Adhesion Tester NOVOTEST SM-1M
Application of the device
Adhesion tester SM-1M is a device for measuring the adhesion value of bitumen pipe insulation and other insulating coatings which are based on bitumen. Adhesion tester SM-1M is a mechanical device which allows to determine the adhesion value of quality and quantity, by measuring the strength of sticking the bitumen insulation to the surface of the pipeline.
Adhesion tester of bitumen insulation allows user to take measurements during testing; planned inspections of steel structures and pipelines after their installation, and also after performing the repairs in order to identify defects during the application of the insulation, as well as for the subsequent monitoring of the quality of performed works. The device has been successfully used in the “field” and in the laboratory (workshop) conditions.
